AQX System Controller limiter settings
Reminder:
AQX controllers must only be configured by fully qualified electro-acoustics technicians as
mistakes could prove costly. Switch off the AQX controller and ensure that the mains plug
is removed from the power socket.
To set AQX limiters correctly:
1) Remove the AQX controller lid
2) Unplug and temporarily remove the AQX top pcb (printed circuit board). You will need to
squeeze the nylon pillar latches gently with a small pair of pliers taking care not to
damage adjacent components
Configure the 4-way links J11, J12, J13 & J14 on the AQX motherboard - one 4-way link
for each output. Configured the links to suit the relevant power amplifier gain – see the
table overleaf.
Jumper allocation:
For your convenience, Martin Audio power amplifiers are supplied set to 32dB
gain. See the 32dB line on the following table for suitable limiter settings.

gain based on its maximum output and sensitivity figures. This spreadsheet also includes a handy
table for converting rms voltages to dBu or dBV.
